Overview

A posterior vaginal prolapse occurs when the thin wall of tissue that separates the rectum from the vagina weakens, allowing the vaginal wall to bulge. Posterior vaginal prolapse is also called a rectocele (REK-toe-seel).

Childbirth and other processes that put pressure on pelvic tissues can lead to posterior vaginal prolapse. A small prolapse may cause no signs or symptoms.

If a posterior vaginal prolapse is large, it may create a noticeable bulge of tissue through the vaginal opening. This bulge may be uncomfortable, but it's rarely painful.

If needed, self-care measures and other nonsurgical options are often effective. Severe posterior vaginal prolapse might require surgical repair.
